Assault shaft - Can anyone fill and redrill roll pin hole?

Soo... I attempted to have some Assault shafts made, and due to doing a small # of them and the shop saying they'd be hand made instead of CNC, the quote was very high.. I won't be able to get any made :-(

If there's enough interest, perhaps we can persuade one of the repro heros to help us get it done. If not, I need a solution.

The thing with my Assault shafts, and I'd assume most, is that the pivot ball is secured by a roll pin in the shaft. It's supposed to pivot on the Y-axis, but got force along the X-axis, which wore the roll pin hole larger. My sticks had nails installed at some point to secure the pivot balls. I got new/NOS of just about everything stick related except the shafts themselves.

Is there a way to reliably fill the hole with a weld, then precisely redrill so that the new roll pins fits tightly as it should? If a reputable KLOV'r can do this for me, I'd be willing to ship them and pay for the service. Pic of the issue below:

You could possibly have someone braze on more material and then shape it down, either on a lathe or by hand with a file. Maybe even rig up something with a drill. Definitely possible to do though.

I'm not familiar with those parts, but my initial feeling is it would be easier to use an oversize roll pin.

I'm also considering drilling it oversize for a sleeve, but the larger roll pin is another idea. Really, the oversized roll pin is probably the way to go. As long as it's very tight when assembled, it should be good for another 25yrs.
 
How do those work? is it a shaft inside a shaft? I have a metal fab class next semester and I can choose my own projects.

No, this is one solid piece. It would have to be turned on a lathe, then precise holes drilled. Oh, and the shaft is drilled so that it's hollow.
 
Can't you just put a new hole 90 degrees from it and ignore the old hole?

Edit: or are there other features on the shaft that will be twisted... Can you post pics of the entire piece?

IMHO, somewhat less likely that it was gun-drilled. More likely that the base stock was a thick-walled tubing. Carefull measurements (like with calipers) of the ID and OD would help determine the likely stock.

There are 2 threaded holes on each shaft, 90 deg from the roll pin holes, that are used to secure the plastic handles, so redrilling 90 deg off probably wouldn't be optimal.
